NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY INC., OF SYRACUSE, NEWYORK, A. CORPORATION OF NEW YORK MEANS ron'surron'rme 'rnn OVERI-IANGINGENDS on THE BUCKS or rnnssine MACHINES I v Application med Ma 3,

This invention relates to pressing machines as garment and laundrypressing machines of the jaw or-platen type in which one of the pressingelements is a platen or a buck supported at or near one end with itsother end overhanging or free, and has for its object, a particularlysimple and efficient means for supporting the'overhanging end of thebuck, which means is movable into and out of its operative or bracingposition so that when it is out of its operative position, garmentsandother articles can be readily sleeved on the overhanging portion of thebuck and when it is in operative position the overhanging end of thebuck will be braced or supported for the pressing operation.

The invention consists in the novel features and in the combinationsandconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawing, in which like characters designate corresponding parts in allthe views.

Figure 1 is an enlarged fragmentary elevation of a pressing machineembodying my invention. L

Figure 2 is a side elevation of a pressing machine to which my inventionis'applied.

The pressing machine is here shown as of the conventional type includinga buck 1,. a head 2 movable toward and from the buck y. a suitablestationary bracket or goose neck 8 located at or near one end of thebuck so; that the greater part of the 'buck'is supported and overhangsthe frame and a retractable and means-for actuating'the head. i

The buck 1 is supported onthe frame brace means automatically engagesthe unsupported buck portion to brace itas the head comes down on thebuck with great pressure, and backs away to free the buck as the pressopens.

The movable means for supportin or bracing the overhanging end of thebuc during the pressing operation is movable out of such position topermit the arranging or s'leeving of the garment on the buck, andcomprises'a brace arm 4 pivoted at 5 to the frame and movable in alateral direction or in a direction endwise of the buck into and out of1928. Serial No. 274,928.

controlled by the means which controls the opening and closing of thehead. v

' In the illustrated embodiment of this invention, the head is closedby. power "mechanism. The head 2 isusually carried by a lever 6 pivotedbetween its ends at 7 to a standard-8 rising from the frame andthislever 6 is actuated by powermechanism as a cylinder 9 supported by the'frame'or a portion thereof beneath the buck. A piston movable in thecylinder has its rod 10 00-11- nected through suitable motiontransmitting mechanism to the rear arm of the lever '6. This piston,which is movable in the cylinder 9, is single acting and the presscloses against the influence of springs 11 which open the p'e'ssfwhenthe force tending to hold it closed i's 'released. The motiontransmitting means between the piston rod 10 and the rear arm of thelever 6may be-of any suitable form, size and construction and includesin part, a lever 12 which fulcrums on the frame and the front end ofwhich is pivoted at 13 to the piston rod and the rear end of which isconnected through toggle mechanism,not shown, to the rear arm ofthelever 6. It is suflicient for an understanding of this invention'tobear in mind that during the out stroke of the piston in the cylinder9,the head 2 moves toward the buck to close the press and when thepressure in the motive fluid in the cylinder 9 is released, the headmoves away from the buck to open the press under the influence of thesprings 11. The flow of motive fluid'as air to and from the cylinder 9is controlled usually by a pair this invention and it is sufficient foran understanding of this invention to bear in mind that the push buttons14k and 14L are depressed and held depressed until the press is closed,when air pressure passes back from the cylinder through pipes 17 and 18to pressure operrated devices or diaphragms which act to hold the valvesoperated by the buttons 14, 14 in their operated positions, andthat toreleasethese valves, a manualmember 16. is operated which exhausts theair from the holding means ordiaphragms permitting the valves controlledby the push buttons 14, 14 to return to their normal positions. o Thedual control forms no part of this invention and a single manual may beused. The means for operating the brace member 4.- which. supports theoverhanging end of the buck is, here shown as a cylinder 21 having apiston movable therein, the rod 22 of which is pivoted at 23. to one armof a bell crank lever 24 pivoted at 25 to the :frame. The other arm ofthe bell crank lever is pivoted at 26 to a'link 27 pivoted at 28 to thelever 4. The link 27 and the arm of the bell crank lever constitute, atoggle. I

' The piston within the cylinder 21 moves upwardly on its power strokeand the lower end of the cylinder 21 is connected by a combined intakeand exhaust pipe 29 to the pipe 15; When the push buttons 14, 14* rpressed, the air passesbothto the cylinder 9 and the cylinder 21 thusactuating the head 2 andmoving the supportinginember tunder the free endof the buck. When the release lever or member '16 is.operated,-the airexhausts from bothcylinders 9 and 21, through one or both of the pipes15, 15 and fromthe cylinder 21thro'u'gh the pipes 29 and 15 or 15? sothat the member 4: moves to its inoperative position, that is, thedotted line position 1.
